Silver Butterfly Earrings, Just curiosity as to era

this stamp ?

 

Yep, Mexican. Based on a pre-Columbian design, etc, etc......
Would love to see the earrings though.

 

Ah, there they are. Pretty, handmade silver filigree.
I can't see what is stamped above Mexico, is it the usual hecho en.. ? I think these are 1950s.

 

Hit the wrong button prior to photos not enough coffee yet Lol!! Thank you AJ that was my guess , what hard work that would be !! And abover says SILVER is what it looks like -They are very pretty , any suggestions how to clean silver?

 

In that case they could be slightly older. The mark 'silver Mexico' is generally pre 1950, although some still used it after 1950.
They look pretty clean to me, but you can start with some soapy water to get any dirt out. After that use a silver cleaning cloth, sunshine cloth in the US. Be gentle with the filigree.

 

They look like 50s to me, or maybe late 40s. The simplest way to clean them up would be to wear them; skin oils remove tarnish nicely. It'll transfer it to your skin, mind....

 

Nice earrings ... does the design of the screw back also help to identify the date?

 

Very Good Question , AJ do you by chance know the answer to that??
